Winchester Garrison Grounds Flood Alleviation
Winchester
The Winchester Garrison Grounds Flood Alleviation Scheme addressed long-standing surface water drainage issues in the south-western area of the site. New land drains were installed to intercept surface water and connect into the existing drainage network discharging to the River Itchen. Integrated with the boundary watercourse and supported by new manholes and chambers, the scheme has improved drainage performance, reduced flood risk, and enhanced the usability of the open space.
